We develop a theoretical model of human skill formation and emigration. Additionally to existing brain drain models, we partly endogenize the heterogeneity of the individuals, by introducing aspirations. Emigration of an individual will result in a migration experience, which increases the...

We consider a model of international migration where skills of workers are imperfectly observed by firms in the host country and where information asymmetries are more severe for immigrants than for natives. There are two stages. In the first one, workers in the South decide whether to move and...

This paper shows that the migration of educated workers abroad can convey a positive signal about the ability of native talents. When there is uncertainty about the distribution of talents in the donor country and/or about the effectiveness of its education system, migrants may reveal...

Neural networks are tackled through probabilities for neurons to be activated by other neurons. They are represented by doubly stochastic matrices, named brain matrices, the polytope of which is the convex hull of the permutation matrices which are vertices of this Birkhoff polytope. Each...

High-skilled workers are four times more likely to migrate than low-skilled workers. This skill bias in migration - often called brain drain - has been at the center of a heated debate about the welfare consequences of emigration from developing countries. In this paper, we provide a global...

Based on a welfare-maximization model of skilled migration where education generates a positive externality, this paper examines whether the early view regarding brain drain's (BD) negative impact on source countries and the Bhagwati tax (BT) associated with it, is compatible with the recent...
